InfiniBand/fibre optic cable SFP+ BlueOptics MA-CBL-TA-0.5M-BL 0.5m Male/Male

The BlueOptics MA-CBL-TA-0.5M-BL is a 0.5 m InfiniBand / fibre optic cable with SFP+ connectors and male-to-male termination designed for short-range, high-speed connections in racks and adjacent rack systems. Intended for 10G applications, the cable implements a direct-attach twinax design suitable for electrical signal transfer over 0.5 m and is MSA-compliant. It is compatible with hardware platforms that accept SFP+ direct-attach cables and supports common protocols such as Ethernet, FCoE, Fibre Channel and InfiniBand at up to 10 Gbit/s over the specified distance.

Advantages

The cable provides a short, low-latency link with passive twinax construction that requires no active electronics in the cable itself, resulting in low power consumption and simple installation. Its SFP+ male-to-male connectors ensure direct compatibility with SFP+ ports, while adherence to MSA specifications supports broad interoperability across switches, routers and storage systems. The compact 0.5 m length is optimized for intra-rack and adjacent-rack connections and reduces excess cabling.

Suitable for

• Interconnecting SFP+ ports in rack-mounted switches and servers
• Short-distance links between adjacent racks or equipment in data centers
• 10G Ethernet, FCoE, Fibre Channel and InfiniBand connections up to 10 Gbit/s
• Environments requiring low latency and low power passive cabling

Key specifications

• Length: 0.5 meter
• Connector type: SFP+ male to SFP+ male
• Cable type: passive twinax copper (Direct Attach Cable)
• Supported data rate: up to 10 Gbit/s
• Wire gauge: 30 AWG
• Compliance: MSA-compliant

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the devices to be linked, ensuring connectors are fully seated and any retention latches engage. Use the 0.5 m cable for short rack-to-rack or intra-rack connections only; verify that both devices support passive DAC twinax SFP+ modules and the chosen transmission protocol. No additional power or configuration is required for the cable itself, but confirm network settings and port negotiation on connected equipment to establish the 10G link.

Recommendations

For reliable operation, route the cable with minimal bends and avoid tight stress on the connectors. Use this passive SFP+ twinax cable for short-distance links in data centers where low latency and low power are priorities. Verify compatibility with device vendor documentation before deployment and consider testing a sample in your environment to confirm full functionality.
